Your girls looking healthy, the veins are normal and the wrinkle leaves shouldn't make y nervous but keep in min:
Wrinkle leaves/curling up are very common, check your temps ( heat stress ) and humidity ( too much humidity can cause overtranspiration, the plant evaporates more water than the ideal ).
Recommended if its possible : temps 20-25 C° and hr: 60-70%
